Multisensory Interaction of Audiovisual Stimuli on the Central and Peripheral Spatial Locations: A Behavioral Study

Much knowledge has been gained about how the brain is activated on audiovisual interaction. However, few data was acquired about the relationship between audiovisual interaction and spatial locations of audiovisual stimuli. Here, we investigated the multisensory interaction of audiovisual stimuli presented on central and peripheral spatial locations. Firstly, we determined the maximal eccentricity of peripheral spatial location on where stimuli were presented which was 30°. Second, the results of audiovisual interaction showed that the interaction of visual and auditory can have dramatic effects on human perception and performance. Moreover, this effect depended on the spatial locations of presented audiovisual stimuli.
